Calculates distance between points based on a set of long/lat coordinates.
rvn_dist_lonlat(p1, p2, method = "haversine", r = 6378137)longitude/latitude of point(s); can be a vector of two numbers, or a matrix of 2 columns (long/lat).
second point in same format as p1
calculation method as either haversine (default) or vincentysphere
radius of the Earth in metres (default 6378137)
a vector of calculated distances (length of vector based on input)
Calculates distance in metres based on the longitude and latitude of two or more sets of points.
The function uses either the Haversine or Vincenty Sphere methods to calculate the distances.
Function is based on modifications from the geosphere package
scripts for distHaversine and distVincentySphere.
